Question

Magnetic dipole X is fixed and magnetic dipole Y is free to move. Dipole Y will initially:

A. Move toward X but not rotate
B. Move away from X but not rotate
C. Move toward X and rotate Move away from X and rotate
D. Rotate but not translate

Answer 1

When magnetic dipole Y is placed near fixed magnetic dipole X, it will move toward X and rotate to align its poles with the poles of X, according to the principle that magnetic dipoles tend to align with magnetic fields.

Step-by-step explanation:

The question discusses the behavior of magnetic dipoles when placed in the vicinity of each other. If magnetic dipole Y is free to move and dipole X is fixed, when dipole Y is introduced into dipole X's magnetic field, it will experience a force due to the magnetic field created by X.

Magnetic dipoles are akin to tiny bar magnets with a north and south pole and, when placed in a magnetic field, they will align with the magnetic field lines.

This behavior is guided by Essential Knowledge 2.D.3 which states that a magnetic dipole tends to align with the magnetic field vector.

Hence, dipole Y will not only move toward X (if the opposing poles are facing each other) but will also rotate such that its poles align with the poles of dipole X (north to south and vice versa).

Therefore, the correct answer is: C. Move toward X and rotate.

Answer 2

Answer: The correct option is A.

Move toward X but not rotate

Step-by-step explanation:

This is because from the question, X is fixed and y is free to move. Since magnetic dipole of X is fixed, that is it can't move and that of y is free to move, therefore y will move toward x because it's forces of attraction is linear and not rotational and besides X and Y are on a linear path, therefore Y will move towards X that is fixed and it will not rotate since it's linear.
